Pontiac Silverdome/ USHRA Events

I have a question, anybody that has attended the Silverdome for any of the USHRA events should remember this hopefully. When you were entering the dome, they always had a recording playing saying things like "Welcome to the Pontiac Silverdome located in Pontiac, MI." (that my not be exact but im trying my best to recall). And stating some quick policies and what not. Now this might not be the right place but this its a shot. IF anyone remembers what im talking about is there anyone here or know of someone that might have those recordings? Id love to get a copy, please and thank. I know this is probably clear as mud but im trying my best to explain.
